You dont need OCIO node
Latest versions of Blender (5.1+) use OCIO 2.5, but DaVinci Resolve is still only compatible with 2.4 version so newest configs dont work. I just graded image with standart color space transform node (instead of OCIO one) and result is objectively better. Will use only this from now on.
